The HyperJuice Plug is a compact, powerful, and surprisingly stylish backup battery for any device that charges via USB.

Size

The HyperJuice Plug is approximately 4 " long, 3 " wide, and 1" thick. Because this device's power converter is built directly into it, there is no power cable/power brick to lug around.

Features and Quality

A lot of engineering went into the HyperJuice Plug. Most notable, however, is the absence of a power brick. I don't know about you, but I shudder at the thought of keeping track of yet another charge cable, as misplacing one effectively bricks the device. The folks at Hypershop have managed to crack this nut by building the D/C converter into the battery pack itself, which makes charging it as simple as sliding out the A/C prongs and plugging them into an outlet.

Another thoughtful feature (and an important one) is the output current. The HyperJuice Plug puts out a full 10W, which makes it capable of charging even my power hungry new iPad. Many external battery packs output at 5W, which will only charge an iPad when it is on standby, and even then only very slowly.

Perhaps the most attractive feature on the HyperJuice Plug is its capacity. It comes in 10,400 mAh and 15,600 mAh versions, and even the smaller of the two will charge an iPhone 7 times, an iPad 2 twice, and will almost fully recharge an empty new iPad 3rd gen. Further, it can handily charge two devices simultaneously via the two built-in USB ports.

Style

Normally, I don't include a Style section when discussing utility peripherals like external battery packs. However, the HyperJuice Plug is not only a workhorse, it's also got verve. Coming in black, silver, green, pink, bronze, and Bondi Blue, it is reminiscent of the early iMacs. The colored portion of the plug is even made of high-quality anodized aluminum, which feels great in your hand.

Summary

Although the HyperJuice Plug's price point is a bit higher than most external battery packs, its chock full of engineering and design features make it clear where that extra money is going. If you need extreme power on the go, the HyperJuice Plug is the best I've seen.
